Product Detail
Company Profile

CFDPLAS PEEK sample loops are made from striped color-coded PEEK tubing and PEEK fittings.
Each PEEK Sample Loop is supplied with two PEEK hex-head nuts and ferrules. These fittings grip the tubing in two locations for a more reliable connection.
PEEK (Polyetheretherketone) sample loops are used in chromatography to inject a precise volume of a sample into a system.
CFDPLAS PEEK Sample loops are accurately sized for each valve type.
However, with small volume loops, the tolerance on the ID of the tubing (±0.001") can have a significant effect on the volume. Therefore PEEK sample loop volume and loop appearance may differ from batch to batch.
PEEK sample loops Features:
Wide range of volumes available
Chemical inertness: PEEK is resistant to most organic solvents, preventing contamination and interaction with the sample.
Biocompatible :The inert nature of PEEK makes these loops ideal for bioinert applications, such as separating proteins, peptides, and nucleic acids.
Reduced metal contamination: They are a good choice for ion chromatography (IC) systems, preventing transition metals from deactivating ion exchange columns.
Versatility: PEEK loops can be used in a variety of applications and are available in a wide range of volumes, from a few microliters to several milliliters.
High-pressure versions: Some loops, like PEEK-lined stainless steel, combine the chemical resistance of PEEK with the strength of stainless steel to handle high pressures (e.g., up to 1310 bar or 19,000 psi).
Ease of use: Some flexible PEEK loops have straight cuts on the ends for easier installation, and many come with fittings for zero dead-volume connections.

PEEK is a mechanically strong, chemically inert polymer ideal for HPLC applications. Since our PEEK sample loops contain no metals or other extractable compounds, no foreign materials will be introduced into the system. Softener-free polyethylene caps are used to avoid contamination of the tubing.
PEEK sample loops are particularly well suited for separations involving proteins, peptides, nucleic acids or other samples of biological origin as well as in IC systems where metal traces may interact with ionic samples or release transition metals that may deactivate ion exchange columns.
PEEK hex-head nuts and PEEK ferrules provide reliable connections, and avoid twisting of the tube.
